Issue 6 January 2008 Installation 5 - 7
Form-C contacts operate. These alarm contacts are isolated and
referenced as audible, visual, and remote fuse or circuit breaker
alarms. These arbitrary references are provided as a suggested
standard for connecting alarm monitoring equipment.
The signals from the four sets of Form-C contacts from each
alarm module are connected via ribbon cables to an alarm
termination board located at the top of the Mini-Distribution
Bay. This termination board provides a convenient point for
installation to connect alarm monitoring systems. Each set of
contacts is a Form-C or transfer type, i.e., a combination of
normally open (NO) and normally closed (NC) contacts with
one side of each in common (C). Either a closure on alarm or an
open on alarm might be required for the alarm monitoring
equipment.
